As per Vedic Astrology, every planet has a varying speed of movement hence every planet impact one’s life differently. We can understand this by taking the example of Moon; the movement of the moon affects one-zodiac sign in and for 2 ¼ (2 days and 6 hours (54 hours approx.). Instead, the sun does so in 30 days or 30° (30 degrees) in one zodiac sign. Wherein at the same time, for Mars and Jupiter change occurs in one zodiac sign in the Sava year 2 ¼ (2 years and 3 months or 820 days approx.). In the same way, Saturn changes its zodiac in the entire two and a half years. A deep study in the domain of astrology shows that. When these planets transit from their houses, they cannot just affect an individual’s present but can also influence their future as well. The influence of these planets affects even their future generations.  Alternatively, there are many such events already happened in history, which suggests that similar kind of events happen in a different part of the world in specific time duration. For example spreading Malaria, Plague or HIV or another sort of flues which not just impact people from one specific country but also can affect the entire continent or one side of the planet, all these planets transits impact the entire human race one or the other way.
